AbstractThirty‐eight patients with a diagnosis of malignant mesothelioma participated in a semistructured interview to evaluate asbestos exposure, acquisition of increased risk information, and retrospective reporting of cognitive and behavioral reactions (particularly smoking behavior) to risk information. Twenty‐eight patients (74%) had direct occupational contact with asbestos, and six patients (16%) reported indirect nonoccupational exposure to asbestos. Only two (10%) of the directly exposed patients acquired risk in formation from professional sources prior to diagnosis of mesothelioma. The most frequently reported reaction to learning of increased risk of cancer was a denial of the risk by minimizing personal exposure. Few patients reported being concerned about the information of increased risk. Smoking behavior did not change as a result of risk information, nor was there any increase in visits to physicians. Guidelines for psychosocial management of at‐risk groups are recomm
